当在FileWriter中追加"true“时，项从列表中删除

import java.io.FileWriter;
import java.io.IOException;
import java.util.ArrayList;

public class Main {
    public static void main(String[] args) {
        ArrayList<String> list = new ArrayList<>();
        list.add("item1");
        list.add("item2");
        list.add("item3");

        // 删除指定位置的项
        list.remove(1);

        // 删除指定元素的项
        list.remove("item3");

        // 输出剩余的项
        for (String item : list) {
            System.out.println(item);
        }
    }
}

import java.io.FileWriter;
import java.io.IOException;

public class Main {
    public static void main(String[] args) {
        try {
            FileWriter writer = new FileWriter("file.txt", true);

            writer.close();
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
